Definitions
- the present invention relates to powerline communication (PLC) systems for residential,
- the object of the present invention is to provide a scheme that allows different PLC
- the objective of the invention is to allow multiple, non-compatible PLC technologies to
- the concept involves the use of a set of predefined beacons, one set for each competing
- beacons maybe activated only while the device is transmitting and are off otherwise.
- Another key part of this invention is to use data (e.g., signal magnitude, tone frequency, etc.) gathered by the listening process to evaluate and report to higher level processes, out-of- tolerance transmissions (e.g., excess signal strength, out of specification tone frequency, etc.).
- data e.g., signal magnitude, tone frequency, etc.
- out-of- tolerance transmissions e.g., excess signal strength, out of specification tone frequency, etc.
- FIG. 1 illustrates an overview of a typical single home installation of several PLC
- FIG. 2 illustrates a home installation in which the home has both in-home PLC and access
- FIG. 3 illustrates an example of spectrum overlap between in-home PLC and access PLC
- FIG.4 illustrates the TDM with beacon concepts by showing examples of slots and frequency allocations for several different PLC technologies with information from beacons used
- FIG.5 illustrates an example of accommodation by moving spectral segments
- FIG.6 illustrates examples of beacon generator and receiver elements.
- FIG.l shows a typical single home installation of several PLC devices, with different
- LN low voltage
- the other in-home devices communicate with other in-home devices
- the power meter 115 attenuates the signal coming in from the
- FIG. 2 shows a typical in-home installation in which both, an in-home PLC service and an access PLC service are provided.
- the residential gateway 202 including a HPA Access 216
- the PLC Access 222 powerline connects at 234 to a power meter
- PLC In-home powerline 230 As is shown, four PLC
- Application 204 and 206 are a pair of PLC speakers 212 and 214, each with an HPA 218 and 220 and application 234 is a PLC Entertainment Center 238 connected to a HPA 234 and application 240 is a PC connected to a HPA 232.
- FIG. 3 provides an example of spectrum overlap between in-home PLC and access PLC.
- the access devices 300 as shown, operate with an access spectrum between about 1.6MHz and
- FIG. 4 shows examples of three technologies, technology A, technology B and technology
- beacons as explained below, is used to coordinate access to the powerline medium.
- time slots are allocated for different technologies to communicate with like devices during that
- Pre-assigned beacons different assignments for different technologies, are allocated at multiple fixed frequencies.
- FIG. 5 illustrates an example of the concept of altering transmission characteristics
- case A at a frequency between fl and f2 while the normal spectrum 520 content for an access technology is shown in case C, at a frequency between £5 and f6.
- the in- home devices accommodate the access spectrum by translating a spectrum section to a high frequency as shown in case B, 510, between £ and f4.
- FIG. 6 shows a few of many ways to implement the beacon generator and receiver elements. There are four possibilities depicted: beacon generator 604 packaged separately,
- beacon generator packaged within a product 628, beacon generator within a product 632 and sharing components (in this case, the AFE 622) and a beacon generator fully integrated into a
- Each set of multiple beacon signals (one set for each PLC technology) are established
- in-band beacons are ones that already exist for that technology (i.e., in-band beacons).
- powerline medium to attenuate signals selectively, by frequency, along the length of the network.
- appliances such as hair dryers, vacuum cleaners, blenders etc.
- receiver on a given powerline network will have at least one beacon to use.
- parameters for policing will change depending on which technology is used and this will be determined once a beacon is detected.
- the accommodation mode can be switch back to normal as needed. That is, when no beacon activity is sensed, devices can revert to their normal mode of operation to regain communications
- Each technology has a particular set of beacon frequency bands assigned to it. These bands are continuously monitored by all network PLC transceivers, of all PLC technologies, for activity. The presence or absence of these beacon signals indicates the need to change to a
- beacon information dictates a switch to accommodation mode, the unit moves, in a coordinated
- a time slot is assigned to each technology, which can communicate
- the time slot is pre-determined as is the set of
- beacons used to broadcasts its existence on the network.
- the beacons would be use for time slot timing, sequencing and other features.
